Investigating Agency: NTSBNTSB
Category: Accident
A Cessna 525A, N129SG experienced a significant damage event following a runway overrun at Nashville-John C. Tune Airport, Tennessee. The pilot and four passengers were unharmed. The pilot-in-command (PIC) was in the left cockpit seat, while a student pilot, possessing a student pilot certificate, was in the right cockpit seat. The PIC was not a certified flight instructor, yet the student pilot controlled the aircraft for a majority of the flight during the descent and initial approach. The student pilot allowed the aircraft to become high and fast, and the PIC subsequently took over control, resulting in the ground proximity warning system activating repeatedly. Upon touchdown, the antiskid system activated, but insufficient runway remained to stop the aircraft. The PIC reported a failure to consider the wet runway condition. The airplane struck the instrument landing system antennas before stopping. The PIC stated the pilot’s negligence led to the accident.A Cessna 525A, N129SG experienced a significant damage event following a runway overrun at Nashville-John C. Tune Airport, Tennessee.

Description

A Cessna 525A, N129SG, was substantially damaged following a runway overrun at Nashville-John C. Tune Airport, Tennessee, USA. The pilot and four passengers were not injured. The pilot-in-command (PIC) was in the left cockpit seat, and a passenger, who possessed a student pilot certificate, was in the right cockpit seat. The PIC was not a certificated flight instructor; however, the student pilot was at the controls for a majority of the flight. During the descent and initial approach, the student pilot allowed the airplane to become high and fast, and the PIC subsequently took over the controls and continued the approach. During the final approach, the ground proximity warning system announced “sink rate” eight times. After touchdown, the antiskid system activated; however, there was insufficient runway remaining on which to stop the airplane. The PIC reported that he neglected to consider the wet runway condition. The airplane overran the runway and struck the instrument landing system antennas before coming to a stop. The PIC reported that there were no mechanical malfunctions or failures during the flight. As a result of the accident, the operator modified its operational procedures to restrict unqualified personnel from the cockpit during flight and initiated a formal risk assessment program. Probable Cause: The pilot-in-command’s failure to execute a go-around when the airplane was high and fast on the final approach.

Primary Cause

Pilot-in-command’s failure to execute a go-around when the aircraft was high and fast on the final approach.Pilot-in-command’s failure to execute a go-around when the aircraft was high and fast on the final approach.
